Fastag is an old technology concept which has been used in many other countries for many years now. The technology is well tested and proven to be highly effective in managing tolls. Basically, it involves the use of radio frequency for its operation.
How does it work?
The Fastag lanes on toll plazas will have a radio frequency transmitter-receiver device installed on top of the lane structure. It will be placed at such an angle that it is able to read the Fastag pasted on your car front windscreen when it is close to it and moving. Another post describes to place it on car. Once the car approaches the toll, the information stored in the tag is read and is transmitted to the computerised system which automatically deducts the toll charge from your online wallet without you having to pay for it manually. There is a need to keep a minimum balance in the wallet for this very purpose.
Now, let us describe the Fastag. It is a RFID (radio frequency identification) based small chip which stores information about your car, such as Name of the owner, Registration number, model and make of car, engine number, chasis number, etc. Once this chip comes in contact with the radio frequencies of the transmitter placed on top of toll lanes, the transmitter is able to read this information and transmits it to the central control unit for payment deduction.
Fastag Uses Beyond Toll Plazas
While this smart chip is currently being used for toll collection only, it can find a number of other uses in future. The government has elaborate plans to link it to RTO office and with traffic management systems as well.
